Question 178519
A student team examined parked cars in four different suburban shopping malls. One hundred vehicles were examined in each location. Research question: At α = .05, does vehicle type vary by mall location? (Data are from a project by MBA students Steve Bennett, Alicia Morais, Steve Olson, and Greg Corda.) Vehic
Vehicle Type Somerset Oakland Great Lakes Jamestown Row Total
Car............ 44...... 49...... 36......... 64..... 193
Minivan........ 21...... 15.......18......... 13...... 67
Full-sized Van.. 2....... 3....... 3.......... 2...... 10
SUV............ 19...... 27...... 26......... 12...... 84
Truck.......... 14....... 6...... 17.......... 9...... 46
Col Total..... 100..... 100..... 100........ 100..... 400
--------------------------------------------------------------
Chi-Sq Test
Ho: row and column factors are not related
Ha: they are related or dependent
--------------------------------------
Run a Chi-Sq Test to get:
Test Stat: 24.5315...
p-value:0.0172...
df=(5-1)(4-1) = 12
Conclusion:
Since p-value is less than 5%, reject Ho
There is a relation between car type and location
